}

如果要使用TCP_CHECK检测各realserver的健康状态，那么，上面关于realserver部分的定义也可以替换为如下内容：

virtual_server 172.16.100.1  {

    delay_loop

    lb_algo rr

    lb_kind DR

    persistence_timeout

    protocol TCP

    sorry_server 127.0.0.1 

    real_server 172.16.100.11  {

        weight

        TCP_CHECK {

        tcp_port

            connect_timeout

        }

    }

    real_server 172.16.100.12  {

        weight

        TCP_CHECK {

        connect_port

            connect_timeout

          }

    }

}

说明：其中的sorry_server是用于定义所有realserver均出现故障时所用的服务器。
